Abstract
A washing machine in accordance with the present invention includes a mounting member disposed between a stator and a bearing housing. Thus, when a motor is rotated according to an operation of the washing machine, the transmission of vibration, which is generated by a repulsive force of the stator, to the bearing housing can be reduced efficiently. Accordingly, a tub coupled to the bearing housing can be prevented from vibrating due to the vibration of the stator, and noise due to the vibration of the tub can be reduced.
Claims19
A washing machine, comprising:
- a motor including a stator and a rotor;
- a drum drivable by a rotation shaft of the rotor;
- a tub defining a space where the drum is positioned;
- a bearing housing fixed to the tub, the bearing housing including:
- a bearing supporting part in which bearings are accommodated, the bearings supporting the rotation shaft of the rotor;
- and
- a stator clamping part extending radially outwardly from the bearing supporting part;
- and
- a mounting member disposed between the stator and the stator clamping part and configured to reduce vibration transferred from the stator to the bearing housing and the tub,
- wherein the mounting member is coupled to the stator clamping part, and
- wherein the stator is mounted on the mounting member.
A washing machine, comprising:
- a motor including a stator and a rotor, the stator having a front side;
- a drum drivable by the rotor;
- a tub defining a space where the drum is positioned, the tub having a rear side;
- and
- a mounting member formed separately from the tub and disposed between the front side of the stator and the rear side of the tub,
- wherein the mounting member permits relative rotational movement between the tub and the stator, and
- wherein the tub includes a bearing housing,
- wherein the mounting member is spaced from the bearing housing in an axial direction of the rotor, and
- wherein the mounting member comprises:
- a clamping portion coupled to the bearing housing;
- and
- a free portion integrally formed with the clamping portion and reducing vibration transferred from the stator to the bearing housing.
A washing machine, comprising:
- a motor including a stator and a rotor;
- a drum drivable by a rotation shaft of the rotor;
- a tub defining a space where the drum is positioned;
- a bearing housing fixed to the tub, the bearing housing including:
- a bearing supporting part in which bearings are accommodated, the bearings supporting the rotation shaft of the rotor;
- and
- a stator clamping part extending radially outwardly from the bearing supporting part;
- and
- a mounting ring sandwiched between the stator and the stator clamping part and coupled to the stator clamping part to mount the stator on the mounting ring.
A laundry machine, comprising:
- a motor including a stator and a rotor;
- a drum drivable by rotation of the rotor;
- a bearing housing supporting the stator;
- a mounting ring having a first surface and a second surface opposite the first surface, the first surface contacting the stator and the second surface contacting the bearing housing, the mounting ring coupled to the bearing housing to mount the stator on the mounting ring:
- and
- fasteners extending through the stator and mounting ring and secured to the bearing housing.
